Research on the Flow in Centrifugal Pump Impeller : 3rd Report, A Theory of the Impeller, Whose Breadth is a Function of Radius

Abstract

The breadth of centrifugal pump impeller is usually a function of the radius. A method for the calculation of the flow in such cases is presented in this report. The author has treated such case by applying the method of series expansion, the method of generalised displacement flow mentioned in the 2nd report, and the thin wing lattice theory presented in the 1st report. Compeared with other methods, this method has no limitations for the number of vanes and the vane angles. Numerical examples are included.
